It is a romance based conlang which refers to itself as "cagieje" because it is spoken in the city and district of "Ea Cagia" which literally means "the homeland". It is the daughter language of the Castelese language spoken in "Castelstad", with which it is still mutually intelligible.

I need a name for "cagieje" that can be used in English, I tried "Cagian" but that sounds too much like "Cajun". Any ideas?

I'm actually having a similar problem with my conlang. The reason I'm having trouble giving it an English name is because the language isn't actually used in a fictional world or anything... So, um, you can see the obvious dilemma here.
